What IS a k2tog-tbl decrease anyways?

K2tog-tbl means knit two stitches together through the back loops. It is a single, left leaning decrease – this means you are decreasing 1 stitch. It is an alternative to the ssk (slip, slip, knit 2 stitches together through the back loop), or a sl1-k1-psso (slip 1, knit 1, pass slipped stitch over). In the swatch above, at the centreline, I’ve decreased by working a k2tog-tbl, one knit stitch, and then a k2tog, and repeated this pattern on every right-side row.
